hsaudiotag3k - Read audio file metadata

hsaudiotag is a pure Python library that lets you read metadata (bitrate, sample rate, duration
and tags) from mp3, mp4, wma, ogg, flac and aiff files. It can only read tags, not write to them,
but unlike more complete libraries (like
Mutagen), it is BSD licensed, making it
suitable for most projects. It is also backed by a nifty test suite.
